FP3 roaming/APN not working

,

Hello,
I am currently abroad and have a problem. The roaming does not work. We have two phones (Android and eos) with the same service provider. I updated the APN setting on both devices - the roaming on the Android phone works on the fly, on the FP3 with eos (1.2-20220725206061) does not work even after a restart. The APN settings on both devices are the same but I’m not able to connect to the Internet. Any suggestions how I can solve this issue?
Thanks, Otto

Ho @otto welcome to the /e/ forum.

It is interesting that you have a “fully Googled” device with which to compare. This rather confirms my suspicion that carriers are offered a Google service to keep APN fully updated on the device. The first thing I would suggest is to go though the APN in very fine detail, especially as this is a roaming issue. We seem to see APN changing in very small detail with evolving technology.

Pay especial attention to the stings with many entries for instance

type="default,supl,dun,mms"

where one false entry can be fatal in some use case.

I tagged your OP with #apn, you might check other similar threads.

(Maybe … from your report I am not clear if you did the /e/ update after updating APN settings, but it is always possible that an /e/ update could actually revert your APN, idk, but from my experience APN are reverted (from a manually set APN) on wipe data.)

I think this is the case, at least on FP3+ with french provider.

It would help substantiate that assertion if you can show the example of a working APN which is different from the APN list which is used in the base of an /e/ update in the apns-conf.xml found here prebuilt/common/etc/apns-conf.xml · v1-q · e / os / android_vendor_lineage · GitLab

:bulb: It is a very long list but one can simply use Crtl + F to find the carrier’s various APNs in the list.

Hello aibd,

thank you for your reply. The /e/ update I did some weeks ago. Yesterday I reconfigured the apn for both devices the fully-google and the /e/ one and I checked the settings in both devices several times. It seems that the mobile service provider changes the apn “regularly”.
Checking the apns-config. xml file the apn for “HOT Internet” line 522 is outdated the current one is available on the website of the provider [https://www.hot.at/config/faqs/HoT_Android_APN_2022.pdf].
This documetn is in german but you can find the settings on page 5 and 10:

Hello again,

short status update:
In the meantime I updated my device to the version /e/OS 1.3-20220823212869 and the APN/roaming is still not working. The APN settings are correct but I’m not able to get an internet connection.
It seems that there is a newer version available (September 5) . I will keep you updated but it may be a few weeks before I go abroad again.

Best,
Otto

Hi Otto,
my experience with HOT is:
first time in France several years ago - no roaming although the APN was correct. Next time in France (a year or so later) - everything was working.
first time in Finnland 3 years ago - no roaming although the APN was correct, even called HOT (according to them everything should work), but still no roaming. Next time in Finnland - everything was working.
This with 2 “normal” googled android phones.
I think this is a HOT problem, not a problem with your device or OS version. Myself I have an FP3+ running /e/OS using 3 and I have no problems with roaming.

Hi vanukalla,

as I explained in my initial post, we had two devices a “normal” Android Nokia and an e/OS FP3 both with HOT as service provider. I changed the APN on both devices and only the Android device was able to connect to the internet. Same APN on both devices also checking the HOT user account if roaming is allowed. I haven’t had any roaming issues with the FP3 in recent years and I’ve had HOT for years (also with other devices).
Especially if two devices with the same settings and a different operating system behave differently, I would suspect that it is a SW problem. Otherwise I can’t explain why it works on one device and not on the other.

Best,
Otto

Hi Otto,

Has the roaming issue been solved now?
Yes, the OS might be the problem.
On the other hand: it did not work for us with normal Android phones after setting the APN correctly and the confirmation of the provider that everything should work. We had to leave the country and come back later. This happend to 3 persons for 2 countries all using HOT within the last years.
So to me there still is the possibility that it is not entirely OS related.
But these things are sooo annoying! Hope the issue gets resolved for you soon.
